<p>Disclosed is a dishwashing machine, comprising a water supply valve as a water supply unit that carries out water supply within a washing tank; a water level sensing unit that senses the water level of wash water that is supplied within the washing tank; and a control unit. The control unit measures the water supply time from the commencement of the water supply by the water supply valve to the sensing of the water level by the water level sensing unit. Additionally, the control unit carries out water replenishment that continuously supplies water only for a prescribed time after the sensing of the water level by the water level sensing unit, and changes the time of the water replenishment of the rinsing step on the basis of the difference in the water supply time for the washing step and the rinsing step.</p>
